二十二碳六烯酸(DHA)是神经元质膜的重要组成部分。在大脑皮层灰质区,DHA主要存在于质膜磷脂,但同时也可在磷脂酶的作用下从膜上释放下来,以游离方式或通过其衍生物参与多种信号转导。
Background: Dietary fish oils, rich in long-chain n–3 (ω-3) fatty acids (FAs) [e.g., docosahexaenoic acid (DHA, 22:6n–3) and eicosapentaenoic acid (EPA, 20:5n–3)], modulate inflammatory reactions thro...
Background: Docosahexanoic acid (DHA) is an important constituent of the brain. Evidence from well-designed intervention trials of the long-term benefits of increasing DHA intake during pregnancy has ...

Background: To date, most studies on the anti-inflammatory effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in humans have used a mixture of the 2 fatty acids in various forms and...
Background: Specific single nucleotide polymorphisms (SNPs) in the fatty acid desaturase (FADS) gene affect the activity and efficiency of enzymes that are responsible for the conversion of polyunsatu...
Background: Children born preterm are at risk of visual-processing impairments. Several lines of evidence have contributed to the rationale that docosahexaenoic acid (DHA) supplementation of preterm i...
Omega-3 fatty acids (n-3) has shown to improve neuromotor function. This study examined the effects of docosahexaenoic acid (DHA) on complex reaction time, precision and efficiency, in female elite so...
探讨二十二碳六烯酸(DHA)对人肝癌细胞株Bel-7402增殖和凋亡的影响及其机制。方法:用不同浓度的DHA(0,25,50,100,200 μmol/L)分别作用人肝癌Bel-7402细胞24,48,72 h后,用MTT法检测细胞的增殖情况、Western blot检测Bcl-2和Bax蛋白的表达,并分别用流式细胞仪、real-time PCR和caspase-3活性检测试剂盒检测上述梯度浓度的...
很多老年人都服用鱼油保健品,因为其中的主要成分之一DHA是一种对大脑十分重要的成分。但美国一项最新研究却认为,DHA无助于减缓老年轻度至中度认知障碍。
